You can test on all platforms without being a subscriber, but you can only export to flash and HTML5 in that case. If you are having problems, post on the "Ask a Question" section of the forums your logs and what your problem is.
My Stencyl resources are available here:
Cutscenes, RPG Elements, Particles, Map System and many more.

Open a command prompt and run the following commands. Change the first line to match the folder where you installed Stencyl.

Code: [Select]
cd "C:\Program Files\Stencyl"
Stencyl.bat > "%USERPROFILE%\Desktop\stencyl-launch-log.txt" 2>&1

This will create a "stencyl-launch-log.txt" file on your desktop. Please post that in a new issue in the issue tracker.
